Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. application Ser.
No. 13/891,230 filed May 10, 2013, which, in turn, claims the
benefit of U.S. provisional application Ser. No. 61/645,722 filed
May 11, 2012, the disclosures of which are hereby incorporated in
their entirety by reference herein.
TECHNICAL FIELD
[0002] This invention relates to earphones and earbuds, and in
particular, to earphone or earbuds that incorporate physiologic
sensors.
BACKGROUND
[0003] This section provides background information related to the
present disclosure which is not necessarily prior art.
[0004] It is increasingly common for people to monitor their
physiology while exercising. Exercise machines often include heart
rate monitors to measure the user's heart rate, but these of course
require the user to remain stationery at the machine. Chest straps
to monitor heart rate and/or respiration of an athlete have been
developed, but these can be cumbersome and uncomfortable and
therefore, are not widely used.
[0005] Recently, developments in ear-based physiologic monitors
have demonstrated their acceptability for medical applications.
Attempts have been made to incorporate these sensors into earbuds
and earphones. See for example, LeBoeuf, et al., U.S. Pat. No.
8,157,730, for Physiological and Environmental Monitoring Systems
and Methods. However, maintaining the sensors in proper position
for consistent and accurate monitoring remains a challenge.
SUMMARY
[0006] This section provides a general summary of the disclosure,
and is not a comprehensive disclosure of its full scope or all of
its features.
[0007] Generally, embodiments of the present invention provide a
combination earphone and physiologic sensor, in some embodiments,
the earphone is of the type comprising a housing with a speaker
therein, and an enhancer for engaging the user's ear, and
acoustically coupling the speaker with the user's ear. A
physiologic sensor is disposed on or preferably in the enhancer.
The enhancer can have at least one aperture or window therein, so
that the sensor can optically couple to the ear of the wearer to
provide physiologic data.
[0008] In other embodiments, the earphone and physiologic sensor
combination comprises an earphone with an earloop. A transmitter is
provided on one of the earphone and the earloop, and a receiver is
provided on the other of the earphone and earloop. The physiologic
sensor can sense physiologic properties through optical
transmission through a part of the ear between the transmitter and
the receiver.
[0009] Further areas of applicability will become apparent from the
description provided herein. The description and specific examples
in this summary are intended for purposes of illustration only and
are not intended to limit the scope of the present disclosure.

DETAILED DESCRIPTION
[0029] Example embodiments will now be described more fully with
reference to the accompanying drawings.
[0030] A first embodiment of an earphone and physiologic sensor in
accordance with the principles of this invention is indicated
generally as 20 in FIGS. 1-3. The earphone and sensor combination
20 comprises a speaker 22 in a housing 24. An enhancer 26
comprising a body 28 adapted to fit within the ear of the user. The
body 28 has an opening for receiving a portion of the housing 24,
so that the speaker 22 communicates with the interior of the body.
A sound tube 30 projects from the body 28, and is adapted to fit in
the user's ear canal, to deliver sound produced by the speaker 22
in the body 28, to the user's ear.
[0031] In accordance with the principles of this invention, the
earphone and sensor combination 20 further comprises an optical
physiologic sensor 32. In this first embodiment, the physiologic
sensor 32 is disposed in the body 28, and there is an aperture 34
in a wall of the body 28 that faces the user's ear when the
earphone is fitted in the user's ear. The aperture 34 is shown as
oval shaped, but it could be some other shape and size. The
aperture 34 optically connects the physiologic sensor 32 with the
user's ear, so that it can measure one or more physiological
properties, for example, pulse and/or O2 saturation, or any other
physiologic property that can be measured in this manner. The
physiologic sensor 32 may include other associated sensors, not
shown, for example, a temperature sensor for sensing ambient
temperature, gps sensor, pressure sensor, and/or altimeter,
accelerometer for measuring steps.
[0032] In accordance with a second preferred embodiment of the
enhancer indicated as 26A in FIG. 5, instead of the aperture 34 in
the wall of the body of the enhancer, there is a window 36. The
window 36 can be a portion of the wall that is thinned sufficiently
that the physiologic sensor 32 can optically connect with the
user's ear. Alternatively, the window 36 can be a portion of the
wall that is transparent to the wavelengths used by the physiologic
sensor 32. This window 36 can be co-molded when the body is formed,
or it can be formed separately, and inserted into the wall and
secured for example, with adhesive, sonic welding, or other
suitable means. The window 36 is shown as oval shaped, but it could
be some other shape and size. Otherwise, the enhancer 26A is
preferably like enhancer 26, and the other parts of an earphone and
physiologic sensor incorporating the enhancer 26A are similar to
the earphone and physiologic sensor combination 20.
[0033] In accordance with a third preferred embodiment of the
enhancer indicated as 26B in FIG. 6, instead of the aperture 34 or
window 36 in the wall of the body of the enhancer, the physiologic
sensor 32 is mounted on the exterior of the enhancer 26B to
optically connect with the user's ear. Otherwise, the enhancer 26B
is preferably like enhancer 26, and the other parts of an earphone
and physiologic sensor incorporating the enhancer 26B are similar
to the earphone and physiologic sensor combination 20.
[0034] In accordance with a fourth preferred embodiment of the
enhancer indicated as 26C in FIG. 7, the face of the body 28 has a
plurality of apertures 38, instead of just one as enhancer 26. In
this fourth preferred embodiment, there are nine generally circular
apertures 38, arranged in a three-by-three array. The apertures 38
could have some other shape, and there could be fewer or more than
nine such apertures. Individual sensors can be provided for each
aperture, or a single sensor can be provided with the apertures
providing multiple accesses for the single sensor. Rather than
apertures 38, windows of similar shape, size, and arrangement can
be provided. These windows would preferably be like the window 36,
described above. Otherwise, the enhancer 26C is preferably like
enhancer 26, and the other parts of an earphone and physiologic
sensor incorporating the enhancer 26C are similar to the earphone
and physiologic sensor combination 20.
[0035] In accordance with a fifth preferred embodiment of the
enhancer indicated as 26D in FIG. 8, the face of the body 28 has a
plurality of windows 40, instead of just one as enhancer 26A. In
this fifth preferred embodiment, there are nine generally
rectangular windows 40, arranged in a three-by-three array. The
windows 40 could have some other shape, and there could be fewer or
more than nine such windows. Individual sensors can be provided for
each window, or a single sensor can be provided with the windows
providing multiple accesses for the single sensor. Rather than
windows 40, apertures of similar shape, size, and arrangement can
be provided. These apertures would preferably be like the aperture
34, described above. The enhancer 26D also includes channels 42 for
conducting sweat away from the windows 40 to reduce the
interference with the optical connection between the sensor(s) and
the user's ear. While four channels 42 are shown in FIG. 8, there
can be fewer or more channels and they can be oriented differently
to improve their ability to conduct sweat away from the windows.
The channels 42 can be sized to conduct sweat by capillary action,
and can be formed from, or their surfaces can be treated with
hydrophilic and/or hydrophobic materials to facilitate their sweat
conduction ability. Otherwise, the enhancer 26D is preferably like
enhancer 26, and the other parts of an earphone and physiologic
sensor incorporating the enhancer 26D are similar to the earphone
and physiologic sensor combination 20.
[0036] In accordance with a sixth preferred embodiment of the
enhancer indicated as 26E in FIG. 9, the body 28 is shown with a
speaker 22 disposed entirely therein, and aligned with the sound
tube 30. FIG. 9 illustrates that even where the speaker is entirely
contained in the enhancer 26E, there is adequate space in the
enhancer to accommodate a physiologic sensor 32.
[0037] In accordance with a seventh preferred embodiment of the
enhancer indicated as 26F in FIGS. 10-12, the lower edge 44 of the
enhancer 26F has a physiologic sensor 32A and the back edge 46 of
the enhancer has a physiologic sensor 32B. A sweat management
system 48 can be provided at the bottom of the enhancer 26F to
either redirect or absorb sweat to reduce interference with the
sensors 32A and 32B.
[0038] As shown in FIG. 11, the enhancer 26F can have a plurality
of windows 50 in the back edge 46, so that the physiologic sensor
32B can optically couple to the forward-facing portions of the
user's ear. In this seventh preferred embodiment, there are six
generally rectangular windows 50, arranged in a two-by-three array.
The windows 50 could have some other shape and size, and there
could be fewer or more than six such windows. Individual sensors
can be provided for each window, or a single sensor can be provided
with the windows providing multiple accesses for the single sensor.
The windows 50 may be like window 36, described above. Rather than
windows 50, apertures of similar shape, size, and arrangement can
be provided. These apertures would preferably be like the aperture
34, described above.
[0039] As shown in FIG. 12, the enhancer 26F can have a plurality
of windows 52 in the lower edge 44, so that the physiologic sensor
32A can optically couple to the upward-facing portions of the
user's ear. In this seventh preferred embodiment, there are six
generally circular windows 52, arranged in a two by three array.
The windows 52 could have some other shape and size, and there
could be fewer or more than six such windows. Individual sensors
can be provided for each window, or a single sensor can be provided
with the windows providing multiple accesses for the single sensor.
The windows 52 may be like window 36, described above. Rather than
windows 52, apertures of similar shape, size, and arrangement can
be provided. These apertures would preferably be like the aperture
34, described above.
[0040] The sweat management system 48 can be provided at the bottom
of the enhancer 26F, to either redirect or absorb sweat to reduce
interference with the sensors 32A and 32B. The sweat management
system 48 can comprise a plurality of channels, like channels 42
discussed above, to conduct sweat away from the windows 50 and 52.
Alternatively, the sweat management system 48 can comprise a
wicking material that conducts sweat away from the windows 50 and
52. The sweat management system 48 can include a reservoir for
holding sweat conducted away from the windows 50 and 52. This
reservoir can comprise a hollow space, but preferably comprises a
hydrogel that can reversibly absorb sweat and dry out.
[0041] The enhancer 26F can have physiologic sensor 32A and windows
52 and physiologic sensor 32B and windows 50, as shown and
described, or the enhancer can have just one of physiologic sensor
32A and windows 52 or physiologic sensor 32B and windows 50. For
example, as shown in FIGS. 13 and 14, an eighth preferred
embodiment of an enhancer 26G includes a physiologic sensor 32B
adjacent the rearward edge 54. The enhancer 26G has a plurality of
windows 56 in the rearward edge 54, so that the physiologic sensor
32B is optically connected to the forwardly facing portion of the
user's ear.
[0042] In accordance with a ninth preferred embodiment of the
enhancer indicated as 26H in FIG. 15, the face of the body 28 has a
pillow 58 over a window in the face of the body. The pillow 58 is
preferably pliable to engage the surface of the user's ear, and by
this engagement provide optical coupling of the sensor, and
exclusion of sweat. This pillow 58 may be formed by a gel-filled
membrane that is translucent to the optical wavelengths used by the
sensor. This pillow 58 may alternatively be a patch of a hydrogel,
which when exposed to moisture, such as from water or sweat, swells
to form a compliant mass translucent to the optical wavelengths
used by the sensor. Otherwise the enhancer 26H is preferably like
enhancer 26, and the other parts of an earphone and physiologic
sensor incorporating the enhancer 26H are similar to the earphone
and physiologic sensor combination 20.
[0043] An earphone and physiologic sensor in accordance with a
tenth embodiment of the principles of this invention, is indicated
generally as 100 in FIG. 17. The earphone and physiologic sensor
100 comprises a housing 102 containing a speaker (not shown), and
an enhancer 104 for coupling the speaker to the user's ear. The
earphone comprises an earloop 106 for engaging the user's ear. The
earphone and physiologic sensor 100 further comprises a transmitter
108 on the housing 102 and a receiver 104 on the earloop 106. The
transmitter 108 and receiver 110 operate to sense physiologic
properties of the user. Alternatively, the transmitter can be on
the earloop 106 and the receiver 110 can be on the housing 102.
[0044] The foregoing description of the embodiments has been
provided for purposes of illustration and description. It is not
intended to be exhaustive or to limit the disclosure. Individual
elements or features of a particular embodiment are generally not
limited to that particular embodiment, but, where applicable, are
interchangeable and can be used in a selected embodiment, even if
not specifically shown or described. The same may also be varied in
many ways. Such variations are not to be regarded as a departure
from the disclosure, and all such modifications are intended to be
included within the scope of the disclosure.
